NKT has finalized a turnkey offshore repair of the Baltic Cable connecting the power grids in Sweden and Germany after it was damaged due to external impact.
The power cable system was restored within 29 days from the initial fault notification and is now back in full operation.
Speed was essential when an anchor damaged the Baltic Cable power link interconnecting the national power grids of Sweden and Germany during the last days of April. NKT was awarded the contract to bring the 250 km 450 kV HVDC power cable back in operation as fast as possible.
After the initial notification NKT quickly mobilized staff and equipment for localization of the fault, de-burial and cut and seal operation onboard a subcontracted vessel provided by JD Contractor. The initial operation was swiftly conducted and within five days the exact fault position was located, the cable de-buried and cable ends sealed and prepared for repair. Within 29 days the Baltic Cable was repaired after efficient preparations and the final execution completed by the cable laying vessel NKT Victoria.
The damaged cable section was located roughly 20 kilometers outside the Swedish coast at a water depth of 30 meters and NKT completed the repair operation by 28 May even though NKT Victoria had to complete the offshore repair under harsh weather conditions. For the owner of the power cable link, Baltic Cable AB, the swift operation was a success.
NKT is one of the leading companies in the market providing both stand-alone repair operations and customized service packages with the possibility to include the unique 10 days vessel guarantee to ensure the shortest mobilization time in the market and remove uncertainty from the repair operation time.
